Claims.

The invention relatesto a water lift apparatus, and more especially to awater pump.` l

'Ihe primary object of the invention is the provision of a pump of`this` character, wherein through the use `of a stripper head havingadriven cable passing therethrough, the cable being of a specialcharacter, causes water to be lifted from a well, for the discharge ofsuch Water out of the pump during the operation of the latter, the pumpbeingof4 novel construction and is unique in the working thereof.

Another object of the invention is the provision of a pump of thischaracter, wherein the cable of endless arrangement is maintained tautthroughout the lifting operation thereof, to assure maximum workingconditions through cooperation with the stripper head, for continuouswater lifting activity of the pump.

A further object of the invention is the provision of a pump of thischaracter, wherein the water lift cable is supported freely exible andis susceptible of smooth travel in the working of the pump, there beingno oil lubrication required for the successful Working of such pump, andall parts thereof are readily accessible for repairs or replacement, thepump being motor driven for the operation thereof, although it may bemanually actuated.

A still further object of the invention is the provision of a pump ofthis character, which is simple in construction, thoroughly reliable andefficient in operation, strong, durable, possessed of few parts,compact, easy of operation, positive in the working thereof, andinexpensive to manufacture and install.

With these and other objects in view, the invention consists in thefeatures of'construction, combination and arrangement of parts as willbe hereinafter set forth in detail, illustrated in the accompanyingdrawings, which disclose the preferred embodiment of the invention, andpointed out in the claims hereunto appended.

In the accompanying drawings- Figure 1' is a vertical sectional viewthrough a Water well and pump stand, showing the pump constructed inaccordance with the invention installed therewith.

Figure 2 is a front elevation of the pump.

Figure 3 is a vertical sectional view through the stripper head of thepump.

Figure 4 is a sectional view taken on the line 4-4 of Figure 3 lookingin the direction of the arrows.

Figure 5 is an enlarged fragmentary vertical sponding parts throughoutthe several views in the drawings.

Referring to the drawings in detail, A designates generally a portiono'f a water well, which may be of `any well known construction, and Bdenotes in entirety the pump constructed in accordance with theinvention, as will be hereinafterrmore fully described. y

The pump B comprises a stripper head-in the form of a sectionalcylindrical body including the lower and upper sections IIJ and II,respectively, which are inter-threaded at I2 with each other at theirends next to one another. The lower section I0 has fitted thereto at itslowermost end a reducing nipple I3 from which depends at its restrictedterminal I4, a standpipe I5, while projecting from the front side ofthis nipple I3 is a discharge faucet I6, provided with a hand operatedplug valve I1 for the turning on and off of such faucet in the usualwell known manner. The upper section II is formed with an inset seal; I8at its uppr portion for stripper diaphragm I9 held thereon by aretaining nut 20, and this diaphragm is made up of several spacedinherently flexible disks for wiper action on an endless flexible waterlifting cable 2l which travels through the stripper head and passesthrough a suitable clearance in such disks. The stripper head forms awater collector chamber 22 therein below the stripper diaphragm I9, sothat water stripped from the cable 2l will be trapped in such chamberfor delivery to the faucet IB and discharge therefrom on the opening ofits valve I'I. The stripper head has its upper section II vertically xedin a stand top 23 of a stand 24 for the pump B, the said stand beingmounted directly over the well A, as best seen in Figure 1 of thedrawings. The pipe I5 depends a distance withinthe well A into the water25 contained therein for the lifting of the latter by the pump whenoperated.

On the top 23 of the stand 24 is supported an electric power motor 26,its driving shaft 2l carrying a driving pulley 28 having trainedthereover the water lifting cable 2|, which is in the form of a cottonrope, the weave thereof effecting a regular pattern of smallindentations, for water lifting purposes, and such pulley drives thesaid cable. The upward traveling stretch of this cable 2I lifts thewater from the well A, and such stretch passes through thepipe I5, andthrough the chamber 22 to be acted upon by the diaphragm I9 for thestripping and depositing of the lifted water into such chamber, thisWater being let off through the faucet I6 when desired.

At one side of the stripper head and vertically mounted in the top 23 ofthe stand 24 is a guide nipple 29 for the descending stretch of cable 2|in the travel ofrthe latter when the pump is o perating. The lower endof the standpipe I5 has tted thereto one of a pair of spaced guidethimbles 30 which are united by a cross web 3| for their verticaldisposition in receiving the ascending and descending stretches of thecable 2| in the travel thereof.

Centrally of the web 3| is a vertical guide throat or neck 32 for afloating hanger rod 33 carrying a lower guide pulley 34 for the cable2|, the pulley block 35 being fitted with a depending changeable Weight3B, which functions to maintain the stretches of the cable 2| tautthroughout the working period of the pump B. The cable 2| is providedwith a detachable or releasable end coupling 31, so that such lcable canbe replaced when required.

Overhanging the stripper head and the upper drivingpulley of the pump Bis a splash box 38, which is held on the top 23 of the stand 24 forshielding purposes.

What is claimed is: v

1. A pump -of the kind described, comprising a stripper head forming awater collecting chamber, a water lift cable working through the chamberin said head, a wiper diaphragm engaging the cable for stripping waterlifted thereby for deposits in the chamber, a discharge faucet on-thehead and leading from the chamber, power means for operating the cable,means for guiding the cable in its travel, means for holding the cabletaut under travel thereof and a standpipe depending from the head intoa. body of water Within a well and having the cable movabletherethrough.

2. A pump of the kind described, comprising a stripper head forming awater collecting chamber, a water lift cable working through the chamberin said head, a wiper diaphragm engaging the cable for stripping Waterlifted thereby for deposits in the chamber, a discharge faucet on thehead'and leading from the chamber, power means for operating the cable,means for guiding the cable in its travel, means for holding the cabletaut under travel thereof, a standpipe depending from the head into abody of Water within a well and having the cable movable therethroughand -a support for the head.

3.The invention as described in claim 2 wherein the means for guidingthe cable in its travel comprises a pair of spaced guide thimbles unitedfor vertical disposition with said cable by a cross web formed at theirmedial points.

4. The invention as described in cliam 2 wherein the means for holdingthe cable taut is supported by a floating hanger rod, mounted in avertical guide throat formed in the medial portion of a cross webuniting spaced guide thimbles for said cable. l v 5. The invention asdescribed in claim 2 wherein the means for holding the cable tautcomprises a pulley block having a depending changeable weight fittedthereon. y
